2x2 Luxury Hat Campaign Grid

A complex JSON prompt for Nano Banana 2 (Pro) to generate a 2x2 editorial grid for a luxury hat campaign, maintaining the identity of an uploaded reference image while varying lighting, mood, angle, and environment across four frames (golden hour, indoor luxury, sunset glow, night look). The subject must wear a white luxury wide-brim hat and an elegant white outfit consistently. Via YouMind OpenLab prompt library (MIT).
